When you are writing an academic paper, you need to list down all the sources which have been used in the academic paper. This is done through the annotated bibliography. It is a complete list of all the sources which have been used in the paper. What is the difference between the annotated bibliography and the normal bibliography? A lot of differences between these two do not exist. The annotated bibliography is a detailed version of the normal bibliography and contains more information about the sources which have been used.
